- What exactly is UEFI with CSM boot mode? - Super User

- boot - What is CSM option - Super User
Enabling CSM Mode causes quantifiable performance degradation and should never be enabled (even when this answer was written, there were only a few distros lacking EFI boot, with all gaining EFI boot by the end of 2017 - Windows has supported EFI boot since Win7) Post-2017, CSM Mode serves no practical purpose beyond booting to a legacy
- I am changing from CSM BIOS mode to UEFI BIOS mode. Is it safe?

- Should I install an OS using UEFI or BIOS (legacy CSM) boot mode?
It may also be called something along the lines of "Enable UEFI Boot" or "Enable Legacy Boot", or mention the term CSM If there is no such option in your firmware, you're out of luck and have to stick with whatever you've got – on older machines that'll be the BIOS mode; there are also some newer machines (e g the Microsoft Surface line
- I have no UEFI Legacy BIOS boot option. What does that mean?
it depend options offered by Bios firmware, Some Large integrators Like Lenovo unfortunately followed intel and Microsoft recommandations for security raisons and have deleted CSM Legacy Modules ! but mainly have Phoenix's Technologie Bioses you do have Megatrends one, i think it offers you more options Oddly Some modern models still have it
